IMPROVEMENT IN DUMPING-CAR'I'.

The Schedule referred to in these Letters Patent and making part '0! thename.

To all whom it may concern Be it known that I, M. F. WIGKERSHAM, ofSpringfield, in the county of Sangamon, and State of Illinois, haveinvented a new and useful Dumping-Cart; and I do hereby declare thefollowing to be a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- Figure] is a longitudinal section of myimproved dumping-cart, taken in the plane of the line a: :5, fig. 2; and

Figure 2 is a transverse section of the same, in the line 3 y, fig. 1.

' Similar letters of reference indicate corresponding parts in theseveral figures of the drawing.

This invention relates to a dumping-cart designed for use with myimproved street-sweeping machine, for which I have made application forLetters Patent, bearing even date herewith. It'is, however, equallyapplicable to all other purposes forwhich dumpingcarts are usuallyemployed.

The invention consists principally in arranging the main portion of thebody of the cart below the axle, in such a manner as to receive the dirtfrom its rear end, at a comparatively short distance above the ground,and, when full to be swung upon the axle, for duinping or dischargingits contents by the gravity of the latter, and the forward movement ofthe cart.

In the accompanying drawings- Ais the axle, and B, the wheels of adumpingcart, of ordinary Orsuitable construction.

0 is the body of the cart, composed of the sidepieces D,.and curvedbottom E.

The side pieces are elliptical in form, with their forward ends cut offto form the perpendicular front of the body.

The bottom may be constructed of sheet-metal, or other suitablematerial. In this example of my invention, I employ sheet-metal, bent toconform to the lower edges of the side pieces, to which it is firmlysecured, in any convenient manner.

The body is hung upon the axle, between the wheels, by passing the endsof said axle through the side pieces, at about the centre of the latter,as clearly shown .in. fig. 1.

The ends of the axle are rounded, to permit the side pieces to turnfreely thereon.

F are the thills or shafts of the cart, secured to the axle in theordinary manner, but provided, near the cross-bar G, with a fixed board,H, arranged parallel with the cross-bar, at such a distance in rearthereof as to fit within the recess a, in the front end-board I,

is much below the axle, and that its rear end is but a attached to theside pieces, and, together with said board, form the front end of thecart-body.

The boards H and I are locked together by means of the lever b, pivotedto the ibrmer, and adapted to catch over the pin 0, affixed to thelatter, as clearly shown in fig. 2.

d is a hook, attached to the upper side of the axle, by which the cartis attached to the street-sweeping machine, hereinbefore mentioned.

If desired, the. axle A may bebent upward between the ends of thethills, in order to increase the capacity of the cart.

I It will be observed, that by hanging the body 0 upon the axle, in themanner described, its bottom E short distance above the ground, so thatthe labor of filling the cart is greatly lessened. This will be found ofgreat advantage in the construction of railroads, where the dirt isgenerally thrown into dumping-carts by means of shovels.

The cart is dumped by releasing the catch 7) 0, when the gravity of thedirt or load will throw the forward end of the body downward into theposition represented by dotted lines, fig. 1.

As the cart is drawn forward, the front end of the body will be broughtnearly in contact with the ground, into which the projecting pins f willcatch, and as the cart continues to move forward, said front end of thebody will be carried thereby so far backward as to permit the ready andcomplete discharge. of the load.

It will be noticed that the distance from the front end of the body tothe centre of the axle upon which it turns, is of a length nearly equalto the radius of the wheels 13, and that, therefore, the body willeasily clear the ground in the operation of dumping.

The body 0 is so hung upon the axle that, when empty, its rear end willhold the front-board I in contact with thefixed board H upon the chills.

My improved dumping-cart is simple and economical in construction,easily operated by a common laborer, and will reduce the fatigueattending the use of the ordinary dumping-cart, in an appreciabledegree.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is 4 Adumping-cart, having its body hung upon the axle, as described,andadapted to be dumped forward by thegravity of the load, substantiallyas herein set forth, for the purpose specified.

The above specification signed by me, this 22d day M. F. WIGKERSHAM.

of July, 1869.
